This shader is inspired by the night vision effects from the game HALO ODST, using edge detection to outline the terrain and entities. Now you too can feel like you've just dropped from orbit into a blocky, unfamiliar world. The sensitivity of the edge detector and the outline colors are fully customizable. Try it with low brightness settings!
Entity specific outlines available on 1.20 and above for iris/oculus.
With all shader features on, this increased my laptop's 4070 GPU usage from 43% to 56% (+13%).
